FLY-EXIT FOR SCREENS.`

SPECIFICATION forming part of Letters Patent No. 643,335, dated February 13, 1900.

Application iiled May 29, 1899. Serial No. 718,665. (No model.)

To a/ZZ whom t may concern:

Be it known that I, HIRAM N. SHEEK, a citizen of the `United States, residing at Greenwood, in the county of Johnson and State of Indiana, have invented certain new and useful Improvements in Fly-Exits for Screens; and I do declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this to project through the screen; and it consists,

further, in the parts and `combination and arrangement of parts hereinafter `fully described and claimed.

The object of this invention is to provide a device of this character that may be attached permanently to the screen when the same is first made or which may be as readily applied afterward and to various sizes of screens;

A further Objectis to provide such a iiyeXit as shall be lnost effective in alluring flies from a room and which may be cheaply made and be durable and economical in use.

I attain these objectsin myinvention shown herein.

Referring to the drawings, Figure l represents a perspective View of a diminutive window screen and frame in which is illustrated my invention applied thereto; Fig. 2, an elevation of the outer side; Fig. 3, a central Vertical transverse sectional view; Fig. 4, an elevation of the inner side, and Figs. 5 and 6 fragmentary detail views.

Similar letters of reference in the several gures of the drawings designate similar parts.

In practically carrying out my invention I provide what may be termed an inclosure U, which is small as compared to the superticial area of the screen. It is suitably composed of tin-plate painted or of other similar metal or of pressed strawboard or the like and comprises a bottom h, avshort back J, having at each end a curved extension 0at the outer i end of which is an ingress in the side of the inclosure, a front, and sides` converging towardthe top c, atwhich is a conical tubular .exit E, projecting from the line of the ianges b, corresponding to the back, which is otherwise open as constructed, but which is `practically closed bythe screen, against which it may be placed and to which it may be `se-` cured by soldering or in any other suitable manner. The inclosure may be built up as it appears or it maybe stamped out or pressed from a sheet in a single piece. The sides are `preferably vertical for a short distance and then lead conically to the exit at the top, so v will not entera small tube projecting from a surface upon which it may be.

The leadways D Dare essentially alike, `differing only in that one is adapted to the right side and the other to the left-hand side.

They7 each comprise a longitudinal portion They are attached at opposite ends of the bottom h, but to the sides of the inclosure, so as to be above the open ingress-channel F in the sides formed by the curved back O, the open inner end of which is a little distance from the side of the inclosure, so that a y may not be inclined to return therethrough. The construction is such that a fly alighting upon the screen would naturally crawl upward, as indicated by the arrows, until arriving at a lead- Way, each of which extends from the inclosure-ingress downward at a suitable angle to vthe edge of the screen, when it would follow IOO inclosure I provide an open way I below a vertical slide-door G, having a lip g resting normally upon the tops of the guide-cleatsj". The door may be further raised and removed, if desired, to expose a larger opening I' in the front of the inclosure to gain access to place sugar or fly-poison into the part t', divided off as a receptacle by a vertical partition I-I in order to attract the flies thereto.

The whole device may be attached by means of the beads or cleats a, which are usually employed to secure the screen to the usual frame A and as a facing, the flanges b d d being suitably adapted for this purpose, and they also afford a surface for soldering, but may be dispensed with and other suitable means employed instead whereby to secure the device.

It will be obvious that the inclosure may be form ed of wire-netting or perforated metal, l

but I preferably employ imperforate sheet metal, as then the light would enter from the outside of the building and attract the liy to proceed outward, particularly when the room of the building is darkened somewhat. The bottom h maybe constructed so as to be depressed at the center, if desired, so as to lead anapproaching fly at the outside upward and y across to the end and channelF.

The advantage in providing the inclosure is in `permittinga fly-,after entering it to have sufficient freedom of movement to avoid its noticing that it is entrapped against returning, so that it may leisurely continue onward and upward instead of dashing vabout in excitement and warning others away in an effort to return, and it is obvious that the exact form shown need not be adhered to in construction within the scope of inyinvention. The inclosure may be provided with a permanent perforated back; but the screen suitably provides this.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A fly-exit device provided with an inclosure comprising a close bottom, a front and sides, all formed up so as to provide a compartment wherein the ies may be at ease, ingress-openings formed at the sides above the bottom an d ingress-channels having their walls projecting into the interior of the inclosure, a leadway at each of the ingresschannels, and an exit from the inclosure.

2. A fly-exitdevice comprising an inclosure struck up from sheet material so as to provide a bottom, a front and short vertical sides above which are continuing sides converging at thetop, an ingresschannel having the Walls thereof projecting inwardly from each of the vertical sides above the bottom, leadways extending from the ingress-channels, and an exit from the inclosure.

3. A fly-exit device comprising an inclosure, an exit from the inclosure, an ingress-opening at each side of the inclosure above the bottom thereof and provided with a channel having the walls thereof projecting inwardly from the ingress-opening, and leadways connected above the ingress-openings.

4. A fly-exit device comprising an inclosure, an exit from the inclosure, an ingress to the inclosure at each side and above the bottom thereof and provided with a channel having the walls thereof projectinginwardly from the ingress-opening, leadways connected above the ingress-openings, an ingress in the front at the bottom of the inclosure, and a slidedoorpartiall y covering the ingress at the front of the inclosure.

5. In a fly exit, the combination of the screen, the inclosure secured to the screen and consisting of a bottom, a front and short vertical sides continuing and converging to the top; a partition rising from the bottom; an ingress at the front of the partition in the front of the inclosure; an ingress in each of the vertical sides above the bottom of the inclosure; an ingress-channel having the walls thereof projecting inwardly from each ingress-opening at the sides, ay leadway connected to each of the vertical sides above the ingress-openings, and an exit from the inclosure. a

6. In a ily-exit, the combination of the screen, the inclosure comprising an imperforate front and bottom and sides and top and secured to the screen, an ingress-aperture in the front of the inclosure at the bottom thereof, a partition within the inclosure extending above the ingress to provide a trap-against return through the ingress-aperture, an `in gress-channel at leach side of the inclosure and extending inwardly therefrom, leadways extending from the ingress-channels at the sides of the inclosure,l and an exit at the top of the inclosure, substantiallyl as set forth.

7. In a fly-exit device, the combination of the screen, the inclosure secured thereto and provided withan ingress-aperture, a slidedoor partially covering such. aperture normally, and a partition within the inclosure extending above such aperture' to provide a receptacle for sugar or the like and a trap against return through such aperture, substantially as set forth.

8. In a {1y-exit device,the combination of the screen, the inclosure secured thereto and provided with an ingress-aperture, a slide-door partially covering such ingress-aperture normally, a partition within the inclosure eX- tending above such aperture, an ingress at each side of such inclosure above such partition and provided with a channel having the walls thereof extending inwardly therefrom, a leadway extending outwardly from each of the ingress-openings at the sides of the inclosure, and an exit at the top of such inclosure, substantially as set forth.

9. In a fly-exit device, the combination of the screen,the inclosure comprising the closed bottom and front and sides and secured to the screen and provided with the ingress-openings at the sides thereof and channels having the walls thereof extending inwardly there- IOO IIO

11. In a fly-exit device, the combination of the screen, the inclosure C provided with the partition H and ingress I and door G, the ingress-channels F F at the sides of the inclesure, the leadways D D' connecting with said ingress-channels, and the eXitE,snbstantia11y as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
